Unstable ice on Coralville Reservoir

CORALVILLE– The U.S. Army Corps of Engineers is warning individuals to be careful on all frozen lakes. With the colder temperatures, ice has begun to form on the Coralville Lake and the Corps is currently lowering the lake level to its winter elevation. The combination of ice formation and lowering of the lake levels will create unstable and dangerous conditions. Ice that is not supported by lake water is at risk of cracking, breaking or giving away at any time. As the ice shelf begins to drop, it can cause a dangerous slope along the shoreline, making it hard to get back off the ice. The worst case scenario would be the development of an ice bridge where there is an air pocket created between the ice and surface of the water. This condition is extremely unstable no matter how thick the ice may be and falling through it in this situation leaves little chance for escape and makes a successful rescue next to impossible. Due to these unsafe conditions, the public is advised to stay off Coralville Lake.
Contact the Coralville Lake Administration Office at 319-338-3543 extension 6300 for more information on lake levels, outflows and inflows. Or send an email to Coralville.lake@usace.army.mil at any time. Also check out the Coralville Lake Facebook page at www.Facebook.com/coralvillelake.
